When the double rows are arranged, the plugging and the pulling are difficult and the bending is easy. The female row is provided with a matched male end, and the female row and the male row are connected with the electrode in a tin soldering mode. The 2.54 pitch pin header is connected with a maximum current of 3A and a voltage of 500 VAC. The contact is stable and can be used for muV level signal transmission.

A spring needle: the plugging and unplugging are convenient, the contact stability is not as good as that of a pin header, the rated voltage is generally 36V DC Max, and the current is 3A Max. The electrode is provided with a matched male end, and the connection manufacturing mode of the male end and the electrode is tin soldering. It is not suitable for muV level signal transmission and is easy to contact badly after long-term use.

Spring plate: the plug is convenient, the contact stability is related to the elasticity of the elastic sheet, but most of the stability is not as good as that of the pogo pin. The electrode is generally provided with a matched male end, and the connection of the male end and the electrode is realized by tin soldering. It is not suitable for muV level signal transmission and is easy to contact badly after long-term use.
